Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Adds richness and body, and its proteins set gently when heated in the milk.
- Kefir
- Adds a tangy, cultured sourness that balances the sweetness and richness.
- Fresh milk
- Forms the liquid base of the soup and carries the richness of the dish.
- Sugar
- Adds sweetness that rounds out the tang of the kefir.
The step that matters
Pouring the egg and kefir mixture into boiling milk. Egg proteins set quickly on contact with hot liquid, which can make small curds. Mixing thoroughly right after pouring disperses the egg evenly, keeping the soup smooth and uniform.
